There are about 28871 clinical studies being (or have been) conducted in Canada. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Overall Objective: To evaluate pain and functional status of patients undergoing surgical correction for lumbar herniated disc, pre- and post-surgery, using subjective (VAS, Oswestry, PSQI, Patient Expectation), as well as, objective measures of physical activity (triaxial accelerometry). Design and Methods: Two groups of subjects will be examined; 1) patients diagnosed with lumbar herniated disc undergoing minimally invasive microdiscectomy (MD), and 2) patients diagnosed with lumbar herniated disc undergoing open microlumbar discectomy (OD). Subjects who agree to participate, will be assessed (assessments listed below) after the diagnosis and prior to surgery. The subject will then be assessed postop and they will continue with follow-up after surgery with a visit at 3 weeks postop. Both methods of discectomy will be discussed with the subject. Once the subject has consented to participate (and prior to surgery), subjects will be randomized with a 50/50 chance of being placed in the MD or OD groups. Subjects will be distributed into the MD group and the OD group using a block randomization method. The study will be single blinded. A longitudinal, within group, comparison will be made to assess the change in the measured parameters. Data involving the MD and OD groups will be accumulated in a cross-sectional fashion. Subjects will be recruited from the referrals to the practices of the Orthopedic and Neurosurgeon Spine Surgeons at the Health Sciences Centre. This encompasses the majority of new and currently managed cases in the Manitoba and Northwestern Ontario. Subjects will be between the ages of 18 and 90. Male and female subjects will be recruited into the study. All patients will clinically demonstrate unilateral lower extremity pain in greater proportion to low back pain symptoms if present. Imaging (CT) will document single level lumbar herniated nucleus pulposis. Exclusion criteria will be cauda equina syndrome, progressive neurologic deficit, bilateral lower extremity symptoms, low back pain more than leg pain, the existence of significant co-morbidity (e.g. cardiac condition, disease, etc.) of any form, and any other physical limitations (musculoskeletal injury). Subjects participating will be required to speak and read English.
The main hypotheses guiding the study are: 1. Stable methadone maintenance patients receiving varenicline will be more likely to maintain abstinence than patients receiving placebo 2. There will be no differences in the type and number of symptoms reported between stable methadone maintenance patients receiving varenicline and placebo 3. There will be no changes in methadone dosage between abstinent and non-abstinent smokers 4. There will be no differences in efficacy, withdrawal symptoms, and safety of varenicline between male and female participants
Approximately 20% of pregnant women experience depression. Untreated depression during pregnancy is linked to decreased prenatal care, difficulties in the pregnancy, poorer outcomes for the baby, and developmental, language, and behaviour problems in the older child. While medication can often offer relief, pregnant women suffering with depression are often reluctant to take medications that may affect the unborn baby. There is little research about the effectiveness of other treatments such as support groups. The investigators project will provide relaxation groups for pregnant women with anxiety and depression. The group will provide a chance to get support from other pregnant women. Two health care specialists will provide information about anxiety and depression. They will also teach the skills for women to manage their symptoms. Women will be asked to complete a few questionnaires to evaluate their symptoms before, during, and after they join the group. They will also be asked to evaluate how the group met their needs.
The main objective of this study is to assess whether a recently-developed bioassay for the molecule "secreted fibrinogen-like protein 2" (sFGL2) can be used to predict the recurrence and/or progression of Hepatitis C Virus disease in post liver transplant patients. The hypothesis is that patients with chronic HCV have higher than normal levels of sFGL2 in their blood both pre- and post-transplantation and that this will inhibit their ability to clear HCV, and influence the progression of HCV disease when it recurs.
The purpose of this study is to empirically determine whether one of 2 surgical techniques commonly used for bile duct reconstruction during living donor liver transplantation results in fewer biliary complications. Also, this study may identify patient group(s) that particularly benefit from a particular technique.
The purpose of this study is to longitudinally follow consenting clinical trial participants who participated in PRECEPT (A Randomized, Double Blind, Placebo Controlled, Dose Finding Study to Assess the Efficacy and Safety of CEP 1347 in Patients With Early Parkinson's Disease). The study will assess the clinical and imaging outcomes relevant to the natural history of Parkinson's disease (PD), as well as determine early biomarkers of the disease.
